TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, ENOGII WAITE, of Franklin City, in the county ofNorfolk, and State of Massachusetts, have invented an improved Machinefor Making Fibrous Bats for Iadding or for being Felted; and I do herebydeclarethe same to be fully described in the following specification,and represented in the accompanying drawings, of which--A Figure 1 is atop view.

Figure 2, a longitudinal section; and

Figure 3, a transverse section of it.v

Figure 4 is a front end elevation, showing the endless apron and themachinery for actuating the striker, to be hereinafter described.. i

This machine is similar in many respects to others in use for the samelpurpose, that is to say, it not only has two cai-ding engines placed atright angles to each other, but an endless apron to remove a bat fromone of such machines. It also has a mechanism hy which a fibrous hat orseries of such is taken from the other carding engine and laid on thelonger bat transversely, the same being in order that the fibres of thetwo bats may cross one another at right angles or thereabouts.

The difliculty which has been experienced with the machines heretoforeused for so making bats for being felted or otherwise employed, has beento operate the two carding engines and the endless apron at the rightspeeds to cause the transverse bats to be laid at the exact or properperiods of time, and without lapping upon one another upon thelongitudinal bat. To overcome this diliicult3v and insure correctdeposits of the transverse bats, I so combine the two sets offeed-rollers of the two bats, by mechanism as hereinafter described,that they nins't always move in unison, or with the requisite speeds forthe correct deposit of the transverse bats on the longitudinal but,however the speed of the endless apron carrying the longitudinalbat mayvary. I have also a new or improved mechanism for removing thetransverse bats from the carding engine and depositing them upon thelongitudinal bat. i

In the drawings, A and B represent portions of the frames of the twocarding engines, which, when in use, are disposed at or about at a rightangle to one another. C is the endless apron proceeding from the maincarding engine, and destined to receive the bats discharged from itsdoffer. This endless apron is supported by and travels on two rollers,I) D', the journals ofthe latter roller being sustained by a frame, F,lbetween which and the main' frame A of the cnrding engine, and so as toextend4 over and across the endless apron, and from the frame B of theauxiliary carding engine, is another frame, G, constructed as shown inthe drawings. The doifer of the auxiliary cai-ding engine is shown atII. In advance of it is a feeding-drum, I, surmounted by a pressure or'top roller, K. The comb of the dofer is not represented, it being commonto the carding engine. In covering the doier with itscnrd teeth orclothing, such is not to go entirely around it, but there is to be anarrow space extending across the surface ofthe doii'er from end to endof it, in which there is to be no clothing or teeth, the circumferenceof a cross-section of the doifer, minus the width of the said space leftunclothed, being equal, or about equal, to the width of the endlessapron. The feeding-drnm or relier I, which receives the bat from thedoier, (such hat bei. combed olf the doifcr and received upon 'the saidroller L) has a diameter about equal to or a little greater than that ofthe doffer. A pulley, a, iixed on the shaft ofthe feedingroller I, hasan endlcss band, b, running around it, and a pulley, c, fixed on theshaft of the roller D of the endless apron C. The said band b, in itscourse from one pulley to the other, is bent at or about at rightanglesaround a guide-post, CZ, or against two friction-rollers arrangedthereon. Thus itwill be seen that there is such a connection between theendless apron, carrying and driving-roller, and the feeding-roller ofthe auxiliary carding engine, that the` proportions of their speeds willalways be alike, whatever may be the speed of the endless apron. Thus,if at any time the speed of the main carding engine `should be increasedor diminished, the speed of the delivery-roller of the auxiliarycartling engine will be increased or diminished in like proportion, soas to cause it to deliver the transverse bats at the proper velocity forthem to be deposited on the hat of the apron without improperoverlapping of any one of such transverse bats on that next to it andpreviously laid. There is also another pulley7 e, fixed on the shaft ofthe feed-roller I. A crossed endless band,f, goes around this pulley andanother pulley,f, iixed on the shaft gof the driving-roller K of thetransverse batearrier, or apparatus or mechanism for removing eachtransverse hat and transferring it to its proper position over and forbeing deposited on the endless apron. This apparatus is composed of tworollers, K L, two endless belts, M M, and a series of card-clothed bars,N N, tc. The belts work-around the two rollers, and the bars extend fromone roller to the other, and are arranged at or about at equal distancesasunder. The outer surface of each of the bars iste be covered with cardteeth or card clothing, as shown at L.

The next part of the machine to be described is the striker, or that bywhich each transverse web or bat, after having been brought directlyover the bat on the endless apron by the bars N N, tc., is forced offthe teeth of such bars and deposited on the bat of' such endless apron.This apparatus may bc thus explained: The said striker, shown at O, iscomposed of a har, t', and a series of other bars, cfc c, extending fromsuch bar z at right angles, and into thev space within the transversecarrier, each of such bars le being provided with a projection, Z, toextend from it as represented I prefer to hinge each of the saidprojections directlyr to its bar, as shown in the drawings, in orderthat they may present no impediments to the movements ofthe carrier. Thebar 2' of the striker is supported by and so as to be capable of beingmoved vertically between two guides or standards m m, projecting upwardfrom the frame G'. The striker is depressed at the proper times by theaction of a spring, P, fixed to the frame G, and bearing upon thestriker, the arrangement of such spring being as represented in iig. 1.A notched wheel, R, fixed on the shaft of the inner roller of thecarrier, operates with a lever, S, whose fulerum is extended from theframe G. The longer arm of the said lever extends underneath and againsta stud, m2, projecting from the striker. The notched -wheel operates onthe lever so as to cause it not only tol raise the striker upward andhold it so elevated the proper length of time, but releases the lever soas to enable the spring to suddenly depress the striker in a manner tocause it to force a transverse bat off the carrier and down upon the batof the endless apron. The shafts of the doffer H, and the feeding-drumI, are provided with pulleys n o, around which an endless crossed belt,p, travels, the same being to cause the speed of the doffer to vary withthat of the feeding-drum, in` order that the bat may be delivered to thefeeding-drum' at the proper rate in proportion to its speed, whethersuch be accelerated or retarded by the endless apron.

Having thus described my invention, what I claim as constituting thesame, is as follows:

I claim the combination of the endless apron C and the feeding-drum I ofthe auxiliary earding engine by or with mechanism whereby the speed ofthe said drum may be controlled by or increased or diminished with thatof the apron, substantially as and for the purpose specified.

I also claim the endless carrier and the striker, made and arranged inmanner, and provided with mechanism for operating them as described.

And I particularly claim the application of the projections of thestriker to their bars by hinges or mechanical equivalents therefor, inorder that the projections may vibrate or move relatively to the bars,so as not to impede the motion of the carrier.

I also claim the combination of the endless apron C, the feeding-drum I,and the doifer H, by or with mechanism whereby the speeds of bothvthedrum and doifer are varied with that of the endless apron, the same Ibeing for the purposes or objects substantially as explained.

ENOCH WAITE.
